Datasheet DC Brushless Fan Motor Drivers Three-Phase Full-Wave Fan Motor Driver BD67173NUX General Description BD67173NUX is a three-phase sensorless fan motor driver used to cool off notebook PCs. It is controlled by a variable speed provided through the PWM input signal. Its feature is sensorless drive which doesn’t require a hall device as a location detection sensor and motor downsizing can be achieved by limiting the number of external components as much as possible. Furthermore, introducing a direct PWM soft switched driving mechanism achieves silent operations and low vibrations. Key Specifications  Operating Supply Voltage Range: 2.2V to 5.5V  Operating Temperature Range: -25°C to +95°C Package(s) VSON010X3030 W(Typ) x D(Typ) x H(Max) 3.00mm x 3.00mm x 0.
